Topsolar 10W 12V Solar Trickle Charger for Car Battery Maintenance

Why do you need the TOPSOLAR Battery Maintainer Trickle Charger?

Modern vehicles are equipped with numerous body control modules, alarm systems, anti-theft mechanisms, and lock monitoring devices, all of which consume battery power. The power consumption of these modules is relatively small, but if the vehicle is left unused or rarely used for a week or two, the battery will gradually discharge until it runs out.

If the battery is not kept charged, its lifespan will be significantly shortened. Sulfation, the main cause of battery failure, is most likely to occur if the 12-volt battery voltage is not properly maintained above 12.4 volts. This is why it's easy for a vehicle's battery to run out of power when the car is parked for an extended period.

Once the battery has lost its charge due to natural power consumption, it may never fully recover the lost power. However, as long as there is sunlight, the TOPSOLAR battery charger and maintainer will generate current to protect your battery from running out of power.

Why does my multimeter fail to detect any voltage when the "Normal Working indicator" is lit normally, under no load and sunlight?

This is a normal occurrence. Our solar panels are brand new products sent directly from the factory. When delivered to consumers, the solar panels are still in an inactive state. When consumers use the panels for the first time, they need to connect a load to activate them, and then use a multimeter to measure the voltage that can be read.

Waterproof and Long-Lasting Material

The TOPSOLAR battery charger and maintainer is designed for long-term use, with waterproof and durable materials for added durability.

Safe & Humanized Junction Box

The Normal Working indicator will turn from black to green when the solar panel has received sunlight and is working normally. If the Polarity Reversal indicator turns from black to red, it means the electrodes are connected backward, and you should connect them correctly immediately.

Solar Accessories

The kit includes 4 suction cups for easy mounting, as well as alligator clips, a cigarette lighter plug, and an O-ring terminal for versatile applications. Carabiner clips are also provided for hanging the charger.

【Light, Simple, Durable】 The TOPSOLAR battery charger is lightweight, weighing only 0.75 pounds, and measures 7.45 x 13.19 inches. Made of waterproof and durable materials, it is designed for long-term use.

【Excellent Circuit Protection】 The junction box features an excellent safety circuit that can prevent the battery from overcharging or reverse charging, as well as protect and prompt the user in case of reverse connection (indicated by the red light).

【Plug & Play】 The charger comes with a heavy-duty 2.1mm x 5.5mm DC plug and an extension cord. The accessories are complete, the installation is convenient, and no professional knowledge is required. There is no need for additional maintenance, as the charger will generate electricity to trickle-charge the battery as long as it faces the sun.

【Applicable to all Rechargeable 12V Batteries】 The TOPSOLAR battery charger and maintainer can safely maintain various 12V batteries, including wet, gel, SLA, EFB, AGM, and deep cycle batteries, making it suitable for a wide range of applications such as cars, motorcycles, trucks, boats, tractors, RVs, and snowmobiles.

【12-Months Warranty】 The solar panels are of excellent quality and come with a 12-month free warranty and lifetime technical support. You can contact the manufacturer for any quality issues within 12 months (Note: Before measuring the voltage, you need to activate the product by connecting it to a load).
